Screw fixing pushrod connectors can be used on bell-cranks and servo output arms at the tail rotor servo, so that the tail rotor pushrod can quickly be installed, disconnected and adjusted. A further advantage is that a hardened steel pushrod can be used. For one helicopter you need two pushrod connectors.

Caution during installation: the barrel of the connector must be free to rotate on the servo output arm or crank. Either use a 2 mm self-locking nut, or apply a little thread-lock fluid when fitting the M2 hexagon nut. Be sparing with the fluid! Tighten the M3 x 4 socket-head cap screw well to hold the pushrod securely. Do not use thread-lock fluid.
